Why should I choose a prefabricated over a conventional house?

An increasing number of citizens opts for prefabricated houses, which can be even 40% cheaper than conventional houses and allow for prescheduled delivery time without lacking in quality.

Why should I choose a prefab over a conventional house?


Why should I prefer a prefab rather than a conventional house? The major advantages that appeal to a lot of people, according to the fabrication companies, include the following:

Economisation

A factory fabricated house can reduce the construction cost. Cost is reduced thanks to the staff's expertise in a specific line of production, as it is the case with the automotive industry. Further reduction is achieved by using robotic machines or tools and machinery, which is difficult to happen at a construction site. Massive supply of raw materials and permanent stock reserves, which facilitate the process of finding materials whenever necessary, also contributes to cost reduction. Finally, cost is reduced thanks to the very good planning which precedes execution.

• Earthquake-resistant structures

A building is actively and passively earthquake safe. Active safety involves the materials resistance and the force exerted on the building by the earthquake. The force exerted by an earthquake on a building equals the building mass (weight) multiplied by earthquake acceleration, which means that the lighter a building is, the weaker the earthquake force. Moreover, as the elasticity of the building increases, the building can more easily return to its initial position preventing thus any strain effects. Consequently, for buildings with only a few floors, such as residential buildings, a wooden framework offers the lightest, most elastic and, thus, most resilient solution to an earthquake. A passively safe building is a building which offers more chances for survival to its residents, should it collapse. Again, a wooden load bearing structure offers greater passive safety thanks to its lighter weight.

Delivery time

A prefabricated house can be delivered in a few weeks, contrary to conventional houses whose construction takes several months, if not years. This is a clearly much simpler process, which relieves the owner from the stress involved in the time-consuming erection of a building. Besides that, in case the construction is on an already existing building or a residential area, minimum nuisance is caused to the other residents. Furthermore, the parts of a prefab are largely fabricated in a factory under strict supervision and in compliance with high standards and specific schedules, without any unexpected events which delay the construction of a conventional house. The time needed for the construction of a prefab ranges from three to six months in total, starting from the day of your order and depending on the fabrication company. The reasons are obvious: factory manufacturing, stable conditions, right scheduling.

• Energy efficiency

Prefabricated houses have thermal insulation properties, which solve one of our current and future problems, that is to say the ever increasing cost of energy.

Predetermined cost

One of the major advantages of prefabs is that construction cost is accurately predetermined and there are no surprises or extra amounts for the buyer's budget.
